IP Routing Features
Configuring OSPF
Enabling Route Redistribution
Note Do not enable redistribution until you have configured the redistribution
“restrict” filters. Otherwise, the network might get overloaded with routes that
you did not intend to redistribute.
To enable redistribution of connected and static IP routes into OSPF, enter
the following commands.
HPswitch(config)# router ospf
HPswitch(ospf)# redistribution connected
HPswitch(ospf)# redistribution static
HPswitch(ospf)# write memory
Syntax: [no] redistribution connected | static
Modifying Redistribution Metric Type
The redistribution metric type is used by default for all routes imported into
OSPF. Type 1 metrics are the same “units” as internal OSPF metrics and can
be compared directly. Type 2 metrics are not directly comparable, and are
treated as larger than the largest internal OSPF metric. The default value is
type 2.
To modify the default value to type 1, enter the following command:
HPswitch(config-ospf-router)# metric-type type1
Syntax: metric-type type1 | type2
The default is type2.
Administrative Distance
The switch can learn about networks from various protocols, including RIP,
and OSPF. Consequently, the routes to a network may differ depending on the
protocol from which the routes were learned. For the switches covered by
this guide, the administrative distance for OSPF routes is set at 110.
The switch selects one route over another based on the source of the route
information. To do so, the switch can use the administrative distances
assigned to the sources.
